“S 106 of the Representation of the People Act 1983, which imposed the penalties for an election candidate found guilty of a corrupt or illegal practice, was compatible with the right to freedom of expression contained in art 10 of the Convention for the Protection of Human Rights and Fundamental Freedoms. The interference with the right to freedom of expression by s 106 and the penalties imposed for breach of that section were proportionate to the legitimate aim of the section.”
